Penis: an unusual site for pilonidal sinus.

Pilonidal sinus affects different regions of the body, gluteal cleft being the most common. This condition affecting the penis is extremely rare with only a few case reports around the world. It is prone for complications like infection, actinomycosis, abscess formation, erectile dysfunction and phimosis amongst others. We present a case of Pilonidal sinus of the penis where a pre-operative diagnosis was made and appropriate treatment in the form of circumcision prevented complications.

Publication rate of abstracts presented at the British Association of Urological Surgeons Annual Meeting.

OBJECTIVE: To determine the number of peer-reviewed publications arising from the abstracts presented at the annual meetings of the British Association of Urological Surgeons (BAUS), and to assess urological trainees' attitudes to research in relationship to the pursuit of Specialist Registrar (SpR) training numbers and their perception of academic urology in the UK. METHODS: Publications resulting from presentations at the annual meetings of the BAUS 2001 and 2002 were searched for using the PubMed database. Variables that might influence the subsequent publication of abstracts in peer-reviewed journals were analysed. Whether institutions from other countries had similar publication rates to those in the UK was also assessed. SpRs were interviewed about their motivation to convert presentations to publications before and after their appointment to SpR training. RESULTS: In July 2004, 142 of 449 abstracts presented at BAUS 2001 and 2002 were published, giving a publication rate of approximately 42% on Kaplan-Meier analysis. The rate of publication appeared to continue to the end of the period of searching for publications. The publication rate arising from UK presentations was lower than that from the non-UK presentations (hazard ratio 0.75, 95% confidence interval 0.49-1.15, P = 0.14). Publication rates from podium and poster presentations were similar. Urology journals accounted for 75% of the publications. Of the SpRs evaluated, 83% did research and presented papers to obtain a training number rather than because of an inherent interest to pursue an academic career. CONCLUSIONS: The conversion rate from BAUS presentation to peer-reviewed publication at 36 months was similar on Kaplan-Meier analysis to that of the American Urological Association (AUA, 38%). Interestingly, the rate of publication from the AUA seems to be faster than from BAUS. In addition, presentations from outside the UK appeared to be published faster than those from the UK. Delegates attending these conferences need to consider this when deciding whether a particular presentation will influence their practice. British urology requires academics who are interested in pursuing high-quality research, and which is presented at major conferences with an intention to publish it in peer-reviewed journals.

Voiding dysfunction after tension-free vaginal tape: a conservative approach is often successful.

The published literature has focused mainly on the efficacy of tension-free vaginal tape (TVT) in correcting stress incontinence with few reports of complications. We report our experience with the first 52 cases of TVT, specifically assessing voiding dysfunction after the procedure. We carried out a retrospective study of patients undergoing TVT surgery for stress urinary incontinence (SUI) between April 2001 and July 2003. Data were collected on period of catheterization, voiding and storage symptoms, their duration and management. Fifty-two women with a mean age 54 years (36-77) were included. Postoperatively, the urethral catheter was removed routinely within 12 h. Twelve patients (23%) failed to void spontaneously and needed recatheterization. Ten of them (83%) were able to resume spontaneous voiding within 3 months. Twenty patients (38%) complained of storage symptoms postoperatively. Sixteen (80%) responded to conservative treatment. Transient urinary symptoms after TVT sling for SUI are common but can usually be managed conservatively.

Role of i.v. urography in patients with haematuria.

OBJECTIVE: Traditionally, patients presenting with haematuria undergo a series of investigations, including urine cytology, cystoscopy, i.v. urography (IVU) and renal tract ultrasound (US). Studies have suggested that the omission of IVU as a routine investigation for painless haematuria does not dramatically reduce the detection rate of malignant conditions. In this large retrospective study we evaluated the impact of the omission of IVU on the diagnosis of renal tract malignancies and other non-malignant but significant conditions. MATERIAL AND METHODS: A retrospective analysis of all patients attending our haematuria clinic between January 2000 and August 2002 was carried out. The diagnostic yields of IVU and a US scan were compared and the significance of abnormalities missed by either modality was assessed with regard to the overall management of patients. Diagnoses were divided into those that were significant and potentially harmful [e.g. tumour, pelvi-ureteric junction (PUJ) obstruction, hydronephrosis] and those that were insignificant and harmless (e.g. simple cyst, non-obstructing calculus). Liddell's exact test for matched pairs was used to test for statistical significance and to give the relative risk of a positive result. RESULTS: A total of 1211 patients were included in the study. When cytology, cystoscopy and US were normal, IVU did not detect any additional malignant pathology. Performing IVU instead of a US scan would have resulted in 74 non-malignant conditions remaining undiagnosed. Similarly, US alone would have missed 64 non-malignant lesions. Six non-malignant but significant conditions, including PUJ obstruction (n = 5) and benign ureteric stricture with hydronephrosis (n = 1), were missed by US but detected by IVU. CONCLUSION: In this cohort of retrospectively studied patients attending a haematuria clinic, IVU could safely have been omitted without decreasing the overall detection of malignant pathologies. Nevertheless, significant non-malignant pathologies would have remained undiagnosed. The authors suggest that US combined with a MAG III renogram could be considered as a first-line investigation instead of IVU. This is likely to result in maximum detection of malignant and non-malignant conditions, while reducing the radiation exposure to the patient.

A unique extra-anatomic urinary diversion!

The ureter is often involved in pelvic malignancy, leading to obstruction, hydronephrosis, and deterioration of renal function. Decompression is provided either by retrograde stenting or by nephrostomy followed by antegrade stent insertion. We present an interesting case where an iatrogenic accident during antegrade stenting led to the placement of the lower end of the stent in the rectal stump. Although this led to a favorable outcome, in that it provided internal continent drainage, it cannot be recommended for emulation. However, it does show that a physician should not only have conventional wisdom but also a good measure of innovation and pragmatism.
